The technical scheme that realizes above-mentioned purpose is:
A kind of condensing reflection device of the present utility model comprises a composite base material, a mirror plastic film and a reflecting coating; Described reflecting coating plating is connected on the described mirror plastic film, and fits on the described composite base material by described mirror plastic film.
Above-mentioned composite base material is by the injection moulding of long glass fibres injection moulding (LFI) technology.
Above-mentioned reflecting coating is connected to described mirror plastic film by the plating of physical vapor deposition (PVD) technology.
Also be coated with a hard conating on the above-mentioned reflecting coating.
The material of above-mentioned composite base material can be selected in polyurethane (PU), epoxy resin, polyureas or the dicyclopentadiene (DCPD) combination of any and variable fiber.Variable fiber comprises: glass fibre, carbon fiber etc.
The material of above-mentioned mirror plastic film is: poly terephthalic acid class plastics (PET), polymethylmethacrylate (PMMA), polycarbonate (PC) or acrylonitrile-butadiene-styrene copolymer (ABS).
Be folded with a heat tracing layer between above-mentioned mirror plastic film and the described composite base material.
The utility model has been owing to adopted above technical scheme, makes it have following beneficial effect to be:
Composite base material utilizes the mold injects moulding by long glass fibres injection moulding (LFI) technology, its good stability of the dimension, and quality is light in the same stiffness situation, and can utilize as required mould to form various supplementary structures, has increased substantially its scope of application; Reflecting coating is used for realizing sun reflection of light, cooperates the shape that generates after the composite base material reaction, realizes the optically focused of sun power; Hard conating plays the effect of protection reflecting coating, prevents that the wearing and tearing of reflecting coating from having guaranteed the spotlight effect that installs; The heat tracing layer can prevent effectively that when temperature is low apparatus surface from forming frost, thereby the Salar light-gathering effect of assurance device also can be added other functions as required; The linear expansion coefficient of composite base material is consistent with the linear expansion coefficient of lower support material, has avoided the creep rupture that brings because of linear expansion coefficient difference.

Embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
Embodiment 1:
See also Fig. 1, a kind of condensing reflection device of the present utility model comprises a composite base material 1, a mirror plastic film 2 and a reflecting coating 3; Reflecting coating 3 platings are connected on the mirror plastic film 2, and fit on the composite base material 1 by mirror plastic film 2.
Reflecting coating 3 is connected to mirror plastic film 2 by the plating of physical vapor deposition (PVD) technology.Reflecting coating 3 is used for realizing sun reflection of light, cooperates the shape that generates after composite base material 1 reaction, realizes the optically focused of sun power.
Also be coated with a hard conating 4 on the reflecting coating 3.Hard conating 4 plays the effect of protection reflecting coating 3, prevents that the wearing and tearing of reflecting coating 3 from having guaranteed the spotlight effect that installs.
The material of composite base material 1 comprises: polyurethane (PU) and variable fiber.
The material of mirror plastic film 2 is: poly terephthalic acid class plastics (PET), polymethylmethacrylate (PMMA), polycarbonate (PC) or acrylonitrile-butadiene-styrene copolymer (ABS).
See also Fig. 3, because composite base material 1 passes through the injection moulding of long glass fibres injection moulding (LFI) technology, its good stability of the dimension, quality is light in the same stiffness situation, has increased substantially its scope of application; Can form reinforcement 12 and mounting hole 11 or other supplementary structures in composite base material 1 bottom by the design of mould.Reinforcement 12 has strengthened the intensity of composite base material 1, and mounting hole 11 has made things convenient for the installation of device and fixed.
Can make by the following method condensing reflection device:
At first, make mould;
Then, a mirror plastic film 2 is covered in the die cavity of mould;
Then, regulate the component of base-material, so that the linear expansion coefficient of the composite base material 1 after the moulding is consistent with the linear expansion coefficient of the propping material that supports composite base material 1.Base-material is injected mould, is a composite base material 1 by the injection moulding of long glass fibres injection moulding (LFI) technology, and mirror plastic film 2 fits on the composite base material 1 simultaneously;
Then, connect a reflecting coating 3 by the physical vapor deposition (PVD) technology in the upper surface plating of mirror plastic film 2;
At last, apply a hard conating 4 at reflecting coating 3.
Embodiment 2:
See also Fig. 2, the difference of present embodiment and a upper embodiment is:
Be folded with a heat tracing layer 5 between mirror plastic film 2 and the composite base material 1.Heat tracing layer 5 can prevent effectively that when temperature is low apparatus surface from forming frost, thus the Salar light-gathering effect of assurance device.
The material that sees also Fig. 5, composite base material 1 comprises: dicyclopentadiene (DCPD) and variable fiber.Be shaped as crank slot shape.
Making the condensing reflection device of present embodiment and the difference of a upper embodiment is:
